What data governance is, really
Eight disciplines. None of them is about programming: all of them are about deciding what a piece of data means and who is accountable for it.
Quality
Define what counts as acceptable data and measure how far the database is from it, by rule and by indicator.
A rule that rejects invalid CNPJ in supplier master data, with a compliance dashboard by area.
The professional does this: writes the rule, measures the deviation and demands the fix from whoever created the record.
The map of careers
Fifteen roles, distributed by seniority and by profile. Where no reliable salary data exists in Brazil, we say so instead of making up a number.
Where you start
Four questions. At the end, the entry track best suited to your starting point, with the first concrete steps.
Where are you coming from?
How much professional experience do you have?
How technically familiar are you?
What is your goal in twelve months?
the five possible entry tracks · answer the diagnostic above to see yours highlighted
Operations-to-governance track
You already live with the problem from the inside. What is missing is method, vocabulary and proof, not business knowledge.
- ✓ Write the glossary of three fields your department uses and disagrees on
- ✓ Learn SQL for querying, enough to check your own database
- ✓ Document a validation rule and propose it to your manager
Control-to-governance track
If you come from finance and controllership, you already think in terms of reconciliation and evidence, which is half of governance work.
- ✓ Translate a recent data error into a measured financial loss
- ✓ Build the business case for a quality rule
- ✓ Take ownership of defining an indicator together with the owning department
Technical track to governance
You already have the tool. The leap is moving from execution to defining rules, roles and policies.
- ✓ Map the lineage of a critical report back to its source
- ✓ Study the DAMA framework and translate it into your context
- ✓ Propose the single source of truth for a data domain
Entry track into the field
With no prior experience, the shortest path goes through master data and quality, where the door is wider.
- ✓ Master advanced Excel and master data concepts
- ✓ Do a public database cleansing project and publish the result
- ✓ Apply for a master data or quality analyst opening
Data leadership track
With your background, the value lies in building the program and defending it to leadership, not in operating the tool.
- ✓ Build the program's business case with measured loss
- ✓ Design the committee, roles and indicators
- ✓ Present the twelve-month roadmap to leadership
The shift to AI
The question everyone asks before joining: won't artificial intelligence wipe out this career before I get there?

What it does not replace
30%
of generative AI projects are expected to be abandoned after proof of concept, among other reasons due to poor data quality.

Data Governance Analyst | Quality, Master Data and LGPD | SQL
About section
I work so that data reaches the decision reliably. I write quality rules, maintain business definitions in the glossary and run the approval workflow for supplier and material master data. I come from operations, so I know the real cost of a wrong record.
Outreach message
Hi, how are you? I saw that you work with data governance at the company. I am entering the field after years in master data and supply chain, and I wanted to understand how your data program is structured. May I ask you two questions?
Quality bullet
I implemented 14 validation rules in supplier master data, reducing rejection due to invalid data from 18% to 4% in four months.
Master data bullet
I designed the material approval workflow with four stages and five departments involved, eliminating the creation of duplicate items.
LGPD bullet
I mapped the personal data inventory of three processes and supported the DPO in responding to data subject requests.
A recurring question
How would you ensure the quality of a supplier record? Answer in three layers: prevention at entry with a rule and a mandatory field, detection with an indicator and a checking routine, and correction with an owner defined per domain.
Conflict question
Two departments disagree on the definition of active customer. What do you do? I take both definitions to the committee with the impact of each in numbers, propose one and record the decision in the glossary. Governance without a decision log does not survive a change of manager.
A question you should ask
Who approves the creation of a master data record in this company today, and is there a quality indicator monitored by someone outside IT?

Who is
- — Those who already work with master data records, procurement, supply chain, finance or systems and want to become the person responsible for the solution.
- — Those who need method and vocabulary to lead a data program, not just one more tool.

- — Those who expect a guaranteed placement in a job or a promised salary.
- — Those who want to work in data science and statistical modeling, which is a different track.
